When the Shewanella oneidensis bacterium "breathes" in certain metal and sulfur compounds anaerobically, the way an aerobic organism would process oxygen, it produces materials that could be used to enhance electronics, electrochemical energy storage, and drug-delivery devices.

Caltech microbiologists have discovered bacteria that feed on manganese and use the metal as their source of calories. Such microbes were predicted to exist over a century ago, but none had been found or described until now.

In northern Chile's Atacama Desert, one of the driest places on Earth, microorganisms are able to eke out an existence by extracting water from the rocks they colonize.

Researchers at Tel Aviv University (TAU) have discovered a non-oxygen breathing animal. The unexpected finding changes one of science's assumptions about the animal world.

Food and energy availability cause physical changes in acid-loving microorganisms that are used to study Earth's climate history, according to research from Dartmouth College.

Microbial communities play essential roles in the biosphere and understanding the mechanisms underlying their functional adaptations to environmental conditions is critical for predicting their behavior. This aspect of microbiome function has not been well characterized in natural high-salt environments.

A boiling point of 5900 degrees Celsius and diamond-like hardness in combination with carbon: tungsten is the heaviest metal, yet has biological functions - especially in heat-loving microorganisms.

Salt-tolerant bacteria grown in brine were able to revive after the brine was put through a cycle of drying and rewetting.

Microbes That Grow On Nitric Oxide

Nitric oxide is a fascinating and versatile molecule, important for all living things as well as our environment: It is highly reactive and toxic, it is used as a signaling molecule, it depletes the ozone layer in our planet's atmosphere and it is the precursor of the greenhouse gas nitrous oxide (N2O).

Last August, Abdelrhman Mohamed found himself hiking deep into the wilderness of Yellowstone National Park. Unlike thousands of tourists who trek to admire the park's iconic geysers and hot springs every year, the WSU graduate student was traveling with a team of scientists to hunt for life within them.

Far below the ocean floor, sediments are teeming with bizarre zombie-like microbes. Although they're technically alive, they grow in slow motion, and can take decades for a single cell to divide--something their cousins at the surface do in a matter of minutes.

Scientists at The University of Texas at Austin's Marine Science Institute have discovered nearly two dozen new types of microbes, many of which use hydrocarbons such as methane and butane as energy sources to survive and grow.

Could a unique bacterium be nature's microscopic power plant? Scientist Moh El-Naggar and his team think it's possible. They work with the Shewanella oneidensis species of bacteria, one of a group of microbes that essentially "breathe" rocks.

High concentrations of heavy metals, like copper and gold, are toxic for most living creatures. This is not the case for the bacterium C. metallidurans, which has found a way to extract valuable trace elements from a compound of heavy metals without poisoning itself.

Search for different life-forms elsewhere is the fascinating area of research in astrophysics and astrobiology. Nearly 3500 exoplanets are discovered according to NASA exoplanet archive database.

A geologist from the University of Aberdeen is taking part in an ocean expedition that aims to discover how far beneath the Earth life can survive.

Cold seeps are places where hydrocarbons, mostly methane, emanate from the sea floor. Unlike the hydrothermal vents, the fluids and bubbles are no hotter than the surrounding seawater, thus the name.

To better understand how microbes behave in extreme environments, one possible proxy, not often considered by astrobiologists, is the human body. Over billions of years of evolution, certain species of microbes inside humans have adapted to environments in the human body that would be extremely rough to many other organisms.

A microbial partnership thriving in an acidic hot spring in Yellowstone National Park has surrendered some of its lifestyle secrets to researchers at the Department of Energy's Oak Ridge National Laboratory.

New Microbes That Thrive Deep in the Earth

They live several kilometers under the surface of the earth, need no light or oxygen and can only be seen in a microscope.
